Quiet area is a scale of the narrow bar width multiplied by the Quiet area.
Blank:When the barcode is reversed, you can specify the size of the blank
area around the barcode.
Bar Barcode Height: the height of the barcode.
Standard Width: It refers to the width of the narrowest bar, i.e. the width of the
unit bar. Commonly a one-dimensional barcode consists of bars and spaces
with four types of width respectively, and 1, 2, 3 and 4 refer to 1, 2, 3 and 4
times the width of the unit bar as per the width size of bars and spaces. The
width of the narrow bar means the width of one unit bar.
Refers to the width of the narrowest strip module, that is, the width of the
reference strip module
The actual width of Bar 2 is a scale of the narrow bar width multiplied by the
width of Bar 2, and the method applies for Bar 3 and 4.
The actual width of Space 1 is a scale of the narrow bar width multiplied by the
width of Space 1, and the method applies for Space 2, 3 and 4.
Blank:A limited area with the same reflectivity as the space on the outside or
in the middle of the left and right ends of the barcode,The actual width of the
blank area is equal to the width of the narrow strip module multiplied by the
proportion of the blank.
